Abstract
Embodiments of the present disclosure relate to a method and an apparatus for identity authentication, an electronic device, and a computer readable storage medium. The method for identity authentication includes: acquiring a signal of a speech of a user; generating feature data with a plurality of dimensions based on the signal, the feature data with the plurality of dimensions indicate different characteristics of the signal; and determining an identity of the user based on the feature data.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A method for identity authentication, comprising:
acquiring a signal of a speech of a user;
generating feature data with a plurality of dimensions based on the signal, the feature data with the plurality of dimensions indicating different characteristics of the signal; and
determining an identity of the user based on the feature data;
wherein determining the identity of the user comprises:
determining a number of sentences associated with a predefined identity and comprised in the signal; and
in response to a ratio of the number determined to a total number of sentences comprised in the signal greater than a threshold ratio, determining the identity of the user as the predefined identity.
2. The method according to claim 1 , wherein the plurality of dimensions comprise at least two of:
speed, loudness, pitch, frequency, and timbre.
3. The method according to claim 1 , wherein determining the identity of the user comprises:
determining a category of the signal based on the feature data;
acquiring a correspondence between the category of the signal and the identity of the user; and
determining the identity of the user as the identity corresponding to the category based on the correspondence.
4. The method according to claim 3 , wherein the category of the signal is determined by an unsupervised learning model.
5. The method according to claim 1 , further comprising:
determining a permission of the user based on the identity of the user; and
triggering a task matching the permission of the user to be executed.
6. An apparatus for identity authentication, comprising:
one or more processors and a memory, wherein the one or more processors are configured to:
acquire a signal of a speech of a user;
generate feature data with a plurality of dimensions based on the signal, the feature data with the plurality of dimensions indicating different characteristics of the signal; and
determine an identity of the user based on the feature data;
wherein the one or more processors determine the identity of the user by performing acts of:
determining a number of sentences associated with a predefined identity and comprised in the signal; and
in response to a ratio of the number determined to a total number of sentences comprised in the signal greater than a threshold ratio, determining the identity of the user as the predefined identity.
7. The apparatus according to claim 6 , wherein the plurality of dimensions comprise at least two of:
speed, loudness, pitch, frequency, and timbre.
8. The apparatus according to claim 6 , wherein the one or more processors determine the identity of the user by performing acts of:
determining a category of the signal based on the feature data;
acquiring a correspondence between the category of the signal and the identity of the user; and
determining the identity of the user as the identity corresponding to the category based on the correspondence.
9. The apparatus according to claim 8 , wherein the category of the signal is determined by an unsupervised learning model.
10. The apparatus according to claim 6 , wherein the one or more processors are configured to:
determine a permission of the user based on the identity of the user; and
trigger a task matching the permission of the user to be executed.
11. A computer readable storage medium, stored thereon with computer programs that, when executed by a processor, the processor is caused to perform a method for identity authentication, wherein the method comprises:
acquiring a signal of a speech of a user;
generating feature data with a plurality of dimensions based on the signal, the feature data with the plurality of dimensions indicating different characteristics of the signal; and
determining an identity of the user based on the feature data;
wherein determining the identity of the user comprises:
determining a number of sentences associated with a predefined identity and comprised in the signal; and
in response to a ratio of the number determined to a total number of sentences comprised in the signal greater than a threshold ratio, determining the identity of the user as the predefined identity.Join the waitlist — get patent alerts
